how can I change K values?
Learner I
for my data science class we need to do different assignments wirth RapidMiner. I don't get a thing tbh! 
We have to cluster the data set using K-means. I did that and now we should experiment with K-values und tell what values make sense. But how can I change them and what does a K-value tell me?

Welcome to the community. In k-means, k stands for the number of clusters that the algorithm determines over the example set. You can check the academy and the help section of rapidminer studio to learn more about each operator. Also, you can iterate over values of K using optimize block of operators (I prefer Optimize Grid), here also if you check the help section you can find examples.
